Description
What is HSFG Hex Bolts
HSFG bolts are high strength structural bolts which have been tightened such as to induce predefined tension in the bolt shank. Due to the tension in the bolt, the interface between the plies (steel members in a joint) cannot move relative to each other because of the frictional resistance.
What are the advantages of HSFG Bolts ?
The main advantages of HSFG bolted connections are their greater stiffness and their ability to withstand alternating forces. Their behaviour under fatigue loading is also better than that of bearing bolted connections.
